MANTLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 636, 7 dated November1899- A nman filed. January 17, 1899. Serial No. 702,456. (No model.)

To all whom it may concern:

Be it known that I, LEOPOLD STIAssNY, a subject of the Emperor ofAustria-Hungary, residing in New York, in the borough of Manhattan,county and State of New York, have invented new and useful Improvementsin Incandescent Mantles, of which the following is a specification.

By means of this invention a mantle can be supported or carried throughvarious stages of manufacture without requiring a loop or like support.In the case of so-called loop-mantles the loop can serve for the supportor suspension of the mantle during manufacture; but if a completedmantle should be required without a loop the cutting or removal of thisloop has been found to be objectionable as, for example, tending toweaken or injure the mantle. A mantle without a loop can be formed andcompleted as set forth in the following specification and claims andillustrated in the annexed drawings, in which Figure 1 shows a sectionalview of the mantle on a temporary support. Fig. 2 shows a like view ofthe mantle on a permanent support. Fig. 3 shows a plan View of Fig. 2.

The mantle 1 is shown with a neck'or contracted portion 2, which can beformed in well-known way, as by sewing or shirring or otherwise drawingtogether or partly closing the neck portion. A collet of metal or thelike could be secured in the mantle-neck; but such collet forms no partof this invention and mantles have been made according to this inventionas Well with as. without collets. The mantle having been provided withits neck is left without a loop, or, in other words, no loop or bail isformed or attached which would extend across or over the neck. Thepassage through neck 2 is thus left free or uninterrupted and atemporary support is inserted or passed through the neck. This temporarysupport can be practically formed with a hook or attaching portion orstem 3 and with a tubular portion having the channel 4 5. The mantle orits neck being suspended or slipped over the support portion 4 5 saidmantle and support can be suspended or placed in or over the flame forthe burning of the mantle, the heat or products of combustion in themantle entering the inlet or mouth 5 and escaping at the lateral outletor months 4 of the channel. The temporary support 3 5, it may be noted,is practically so shaped or of such cross-section as to conform to thecontour desired for the completed mantle or to which the mantle beforeburning is shaped or stretched. The support 3 5 thus also may beconsidered as a conformator or means for shaping the neck of the mantle,as this conformator can be made of any desired size or shape.

The process of burning, shaping, dipping, and drying the mantle isfamiliar and need not be set forth in this application, and when theburned mantle is dry the temporary support is removed and the neck 2 ofthe mantle can now be connected to the permanent support. This latter ispractically formed by a supporting-ring 6, having arms '7, which arefixed or immovably clamped to a larger ring 8, whose stem 9 may besuitably secured or adjusted in a lamp. A m'antlecarrier is shown formedby a tube or eyelet having a contracted portion forming shoulder 10,made to sit against the supporting-ring 6 and fixed or immovably securedto the ring by the upper portion or edge 11 being riveted or flanged. Bythis means the carrier, the ring 6, and ring 8 can be fixed or securedtogether, so as to be immovable and secure against separation or loss.

The neck 2 being slipped over the carrierbody 12 and the carrier beingflanged or widened, as shown at 14, the mantle is connected to thecarrier. By having the neck 2 of sufficient width or of larger diameterthan the carrier-body 12 and by having said body 12 of suitable lengthto allow the mantle to slide along the carrier-body said suspendedmantle is free to swing and also to move vertically, or, in other words,the loosely-mounted mantle is universally movable to a certain extent,so as to escape shocks or strain, which might crack, break, or injurethe mantle.

The unburned or unfinished mantle could of course be connected to thepermanent support 12 and then burned; but an objection to this method isthat the carrier 12 or any of the parts 6 to 12 might be more or lessaffected by accompanying the mantle in its various stages of treatmentand would no longer present the neat or new appearance desired for anarticle exposed in the market. Likewise the expansion and contractionwhich the carrier 12 would undergo if accompanying the mantle in itsmanufacture might be injurious or objectionable for the mantle. Thetemporary carrier 3 5 is so thick or massive and of such small diameterthat its heating and cooling do not injure the mantle.

The temporary carrier 3 is adapted for exposure or rough treatment anddoes not accompany the mantle when the latter is offered to the public.The mantle could have its neck 2 covered or lined with asbestos orsuitable metal, if desired, for strengthening and retaining form, andthe mantles can be of any desired form, as circular or oblong incrosssection. The carrier 12 is shown of circular cross-section; butthis form can manifestly also be changed, as can also that of rings 6and 8. The size or diameter of neck 2 and carrier 12 can also be variedto suit circumstances. By this method mantles can be produced of varyingshapes, sizes, and diameters.

The arms 7 and ring 8, as also ring 6 and carrier 12, might any or allof them be loosely connected; but a firm connection, as seen, is ofadvantage.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a supporting-ring,

and a tubular mantle-carrier suspended therefrom, of a mantle looselysupported by and susceptible of lateral swinging and vertical movementsupon said carrier, substantially as described.

2. The combination with a supporting-ring, and a tubular mantle-carrierimmovably connected with and suspended from said ring, of a mantleloosely supported by and susceptible of lateral swinging and verticalmovements upon said carrier, substantially as described.

3. The combination with a supporting-ring having arms, a larger ring towhich said arms are fixed, and a mantle-carrier fixed to and suspendedfrom said supporting-ring, of a mantle loosely mounted on and aroundsaid carrier and universally movable thereon, substantially asdescribed.

4:. The combination with a supporting-ring provided with arms, a ring toconnect with and support said arms, and a mantle-carrier fixed orclamped to said supporting-ring, of a mantle loosely mounted on andaround said carrier and universally movable thereon, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

LEOPOLD STIASSNY.
